This commit changed to enable the encoder to adjust motion dection speed threshold based on picture size. In addition, cpu-used 1 now does a partition search every other frame instead of every third frame for low resolution inputs. The change has no quality/speed impact for 720p and above. Test showed the change increase encoding time by between 3% to 6% for cpu-used 2 encodiong of 360p sequences. It also has a compression gain about .3%. For cpu-used 2, the change resolved some very disturbing visual artifacts in certain sequences when large block partitionings and transforms are used as a result of copying the partition from a previous frame.
